Ocular circulatory changes following scleral buckling procedures.
The effect of segmental scleral buckling (SB) on ocular circulation was evaluated by measurements of the ocular pulse amplitude (PA) and the ophthalmic artery pressure (OAP). In this study the OAP was defined as the intraocular pressure (IOP) at which the PA disappeared during increasing IOP. Twenty four patients with unilateral rhegmatogenous retinal detachment who underwent SB of varying exte...
متن کاملRefractive changes after scleral buckling surgery.
Pneumatic retinopexy is increasingly recommended to treat some patients with retinal detachment to avoid the complication of induced refractive changes sometimes associated with scleral buckling procedures. Prospective evaluation of refractive changes after scleral buckling procedures was performed in 75 eyes of 69 patients. Encircling scleral buckles caused an average increased axial length of...
متن کاملRegional Changes in Choroidal Thickness Associated With Accommodation.
PURPOSE To characterize the changes occurring in choroidal thickness (ChT) across the posterior pole during accommodation using enhanced-depth imaging optical coherence tomography (OCT). METHODS Forty participants (mean age 21 ± 2 years) had measures of ChT and ocular biometry taken during accommodation to 0, 3, and 6 diopter (D) stimuli, with the Spectralis OCT and Lenstar biometer. A Badal ...
متن کاملAge-related changes in ocular aberrations with accommodation.
This study investigates the changes in aberrations with monocular accommodation as a function of age. Second-order and higher order wavefront aberrations and pupil size were measured as a function of accommodation demand over the range of 0-4 D in the right eyes of 47 normal subjects with ages between 17 and 56 years. Higher order ocular Zernike aberrations were analyzed for the natural pupil s...
متن کاملCiliary muscle morphologic changes with accommodation and axial ametropia.
PURPOSE To use anterior segment optical coherence tomography (AS-OCT) to analyze ciliary muscle morphology and changes with accommodation and axial ametropia. METHODS Fifty prepresbyopic volunteers, aged 19 to 34 years were recruited. High-resolution images were acquired of nasal and temporal ciliary muscles in the relaxed state and at stimulus vergence levels of -4 and -8 D. Objective accomm...
